Scabies is an itchy skin condition caused by a tiny burrowing mite called Sarcoptesscabiei
Nodular scabies: Nodules occur in 7-10% of patients with scabies, particularly young children. In neonates unable to scratch, pinkish brown nodules ranging in size from 2-20 mm in diameter may develop.
Crusted scabies: In crusted scabies, lesions are often hyperkeratotic and crusted and cover large areas. Marked scaling is common, and pruritus may be minimal or absent. Nail dystrophy and scalp lesions may be prominent. The hands and arms are the usual locations for lesions, but all sites are vulnerable.
Secondary lesions: These lesions result from scratching, secondary infection, and/or the host’s immune response against the scabies mites and their products. Characteristic findings include the following:
· Widespread eczematous dermatitis
· Honey-colored crusting
· Postinflammatory hyperpigmentation
· Prurigo nodules
· Frank pyoderma
